Finding radius of a sphere inside a cone

I am trying to solve a problem that I just can't figure out. Here it is: A cone is filled with water. 2 spheres are firmly submerged into the cone. The larger sphere's radius is twice that of the smaller sphere. The volume of water that still remains after the spheres are submerged is 2016pi. What is the radius of the smaller sphere?
